P34
Ritscher
Overview
The P34 Series is a specialized, high-torque motor engineered for the demanding application of electric coffee grinders and mills. Designed to deliver consistent, powerful grinding performance across a spectrum of beans—from delicate light roasts to dense, oily dark roasts—this motor ensures precise control over grind size, minimal heat transfer, and reliable operation for both commercial and premium home use.
Key Features & Advantages
High Torque & Grinding Power: Optimized to deliver high starting and running torque at relatively low speeds, effectively overcoming the initial resistance of whole beans and maintaining steady power through continuous grinding without stalling or speed drop.
Low-Speed, High-Torque Design: Operates at speeds ideal for burr grinding mechanisms (typically in the range of 500 to 1500 RPM under load), minimizing friction-induced heat. This preserves the delicate aroma oils and flavors of the coffee by preventing "heat burning," which can occur with high-speed blade grinders.
Precise Speed Control Compatibility: Easily interfaces with electronic or mechanical speed controllers, allowing users or automated systems to select optimal grinding speeds for different brew methods (e.g., slower for espresso, faster for French press).
Quiet & Low-Vibration Operation: Engineered with precision-balanced components and advanced acoustic damping to reduce operational noise and vibration, providing a noticeably quieter and more pleasant grinding experience, crucial for home kitchens and cafe environments.
Thermal Management & Durability: Constructed with high-temperature rated insulation (Class B or higher) and efficient thermal dissipation pathways. Built to withstand the intermittent yet high-torque duty cycles of grinding without overheating, ensuring long-term reliability.
Compact & Integrated Design: The P34 frame offers a compact yet powerful package, allowing for streamlined integration into the often-space-constrained housings of countertop and on-demand grinders.
Robust Construction for Food-Grade Environments: Designed with materials and surface finishes suitable for use in food-contact applications. Often features sealed bearings or protective covers to resist ingress of fine coffee dust, which can be abrasive and affect motor life.
Typical Specifications
Motor Type: Permanent Magnet DC (PMDC) or specially wound Universal Motor (AC/DC).
Frame Designation: P34 (Industry-referenced series for coffee grinder applications).
Input Power: Commonly DC 12V/24V (for premium/commercial) or AC 100-240V, 50/60Hz.
Rated Power: Typically ranges from 60W to 200W, balancing power with energy efficiency.
No-Load Speed: Up to 10,000 - 20,000 RPM, reduced via gearing or electronic control to optimal grinding speeds.
Mounting: Customized mounting flanges or brackets for direct coupling to the burr assembly shaft.
Shaft: Precision output shaft designed for direct or geared connection to the burr set, often featuring a specific keyway or D-cut for secure torque transmission.
Primary Applications
Commercial Espresso Grinders (Doser & Doserless)
Premium Home Burr Grinders (Conical & Flat Burr)
On-Demand Grinding Systems for cafes and restaurants
Specialty Coffee Brewing Equipment
Why Choose the P34 Series Coffee Grinder Motor?
In the world of specialty coffee, consistency is king, and the grinder is the most critical component. The P34 Series Motor provides the reliable, powerful, and controlled heart that premium grinding demands. By delivering high torque at low, controlled speeds, it enables the precise particle size distribution essential for extracting the full flavor potential of the coffee. Its quiet, durable, and thermally efficient design makes it the trusted choice for manufacturers building grinders that baristas and coffee enthusiasts rely on daily.
Note: Final grind consistency and performance are a system-level result of the motor, burr set, and control electronics. Proper torque-speed matching to the burr set's resistance profile is essential. Customization of voltage, shaft configuration, and control interfaces is available for OEM integration.

ABOUT US
Ritscher group was established in 2006.we always focus on micro-motors for household and industrial electrical appliance.Currently, we have professional micro-motor factories separatlly located in Guangdong & Zhejiang province.It has 50,000 square meters plants and more than 500 employees, annual output is 5 million pcs and has 10 million pcs annual producing capacity.After years development,we built a great reputation in the domestic and oversea market and have the trust from our global customers.
We started our business from shaded pole motors, after 10 years development,our products is enlarged to BLDC motors ,capacitor motors ,synchronous motors,stepping motors,servo motors, and PMDC motors.Our products are widely used for making refrigerators, freezers, micro-wave ovens, air warmers, air exhausters, ventilators,ovens, air filter, massage machines and many other equipments.
To design the lastest technology motors and meet our customers requirments,we have the very capable R&D team,to ensure our products quality ,we have very strict manage system for our production department & QC department,to make our cost lower,we have the very professional purchase department, We dedicate to make every details better than we could do.
To offer quick and better service to our customers in Australia and New Zeland,we set up branch office in Australia since 2017 with exprienced consultant to support the business ,which will bring more customers to get know of us.
We will keep doing our job,move forward step by step to make our business area wider and brighter.
Our company FAQ for you
(1) Q: What kind motors you can provide?
A:For now,we mainly provide Kitchen Hood Motor,DC Motor,Gear Motor,Fan Motor Refrigerator Motor,Hair Dryer Motor Blender Motor Mixer Motor,
Shade Pole Motor,Capacitor Motor,BLDC Motor PMDC Motor,Synchronous Motor,Stepping Motor etc.
(2) Q: Is it possible to visit your factory
A: Sure. But please kindly keep us posted a few days in advance. We need to check our
schedule to see if we are available .
(3) Q: Can I get some samples
A: It depends. If only a few samples for personal use or replacement, I am afraid it will
be difficult for us to provide, because all of our motors are custom made and no stock
available if there is no further needs. If just sample testing before the official order and
our MOQ, price and other terms are acceptable, we'd love to provide samples.
(4) Q: Is there a MOQ for your motors?
A: Yes. The MOQ is between 1000~10,000pcs for different models after sample approval.
But it's also okay for us to accept smaller lots like a few dozens, hundreds or thousands
For the initial 3 orders after sample approval.For samples, there is no MOQ requirement. But the less the better (like no more than 5pcs) on condition that the quantity is enough in case any changes needed after initial testing.
