2009-11-29 Such constant torque is well suited to your belt grinder application for which the torque requirement would be relatively independent of speed. A 3 phase motor is MUCH cheaper than a DC motor of equivalent power however buying salvage or junk or finding at the side of the road changes this equation unpredictably.

2020-2-11 IMHO, a 1" belt grinder needs a minimum of 1HP. VFD control preferred. Max speed 120 Hz on a 4-pole sheaved to get at least 4000 FPM on the belt. 5000 FPM preferred. A 4" belt needs at least 2 HP with same speeds. 3 HP motor is better. RWO.

2021-6-18 Some grinders require the motor to be face mounted and the jack shaft is not possible. For an 1800 RPM motor I recommend a 7" drive wheel. This will get your belt speed closer to the abrasive manufacturer's specified speed. Most belts do a good job around 4000 to 5000 feet per second. I have a tool for figuring out your belt speed here. You can run it with a 4" wheel, but it will be severely under speed.

2016-8-14 Most brushed DC motors can be controlled using a PWM (Pulse Width Modulation) speed controller. This delivers full voltage/current to the motor in short pulses. The shorter the pulse the slower the motor goes, the wider the pulse the faster it goes. See the diagram below for what PWM looks like. Regarding the belt speed to RPM calculations.

2019-8-12 The rule-of-thumb for belt grinder motor power in industry is 1 HP per inch of belt width (750W per 25mm). Standard industrial motors tend to be designed for a maximum continuous mechanical speed of 3600 RPM to cover 2-pole motors running on 60 Hz mains in those parts of the world that use it.

2021-6-18 The speed of a motor is important but can be compensated for by using the VFD to increase the motor speed or by using a larger diameter drive wheel to make up for lack of speed. Pulley, shaft and belt arrangements can also be used to compensate for motor speed. However, not all grinder designs will accept these extra moving parts.

2019-11-18 That meant for the two-inch belt I needed a 1.5kW motor since the price difference was only a little bit I decided not to fuzz around and I got the 2.2kW motor at 3000RPM. This motor is 3HP. It’s a beast! To get variable speed control on the motor I bought a 3 Phase 230V motor which I’m connecting to a

2020-6-18 The motor can be face mounted for direct drive with VFD speed control, or belt driven with step pulleys for 3-speed on a fixed speed motor. I'd say don't spend $700 on a sub-par grinder when ~$1000 will get you one that you can expand indefinitely.

2010-11-25 v = rω Equation 1. where v is the linear velocity in meters/minute, r is the radius in meters and ω is the angular velocity in radians/second.

2009-2-6 I want to build a 2" by 72" belt grinder. I want a maximum speed of 5000 fpm. I want a VFD. It looks like I can achieve this with either a 1725 RPM motor, sped way up for 5000 fpm, or a 3450 RPM motor, which would run at around 5000 fpm at 60 Hz and would have to be slowed down for lower speeds. I figured the faster motor was the better choice ...

2010-10-18 6. Nov 16, 2009. I am getting ready to build a 2x72 belt grinder, and would really like to have a variable speed controller on it. I can't afford the variable control units that come on most belt grinders. A carpenter friend suggested using a router speed controller that can be had for $50 instead.
